Square Enix is celebrating MMO Final Fantasy XIV: A Realm Reborn having achieved 4 million registered users, discounting Free Trial versions, and has announced a "free log-in period" to run from this weekend.

The free game time is only for those "taking a break" from Eorzea, and to let them sample the changes from the recent Patch 2.51. They did a similar albeit smaller free weekend at the start of February.

Final Fantasy 14: A Realm Reborn is gearing up for this year's Heavensward expansion with a big climax that will see the end of the core game's main plotline.

Patch 2.5, otherwise known as Before the Fall Part One, has now been released, offering “roughly two-thirds of the final main scenario quests”, three new dungeons, and the conclusion of the Crystal Tower questline and the World of Darkness.
